91 RON unleaded petrol must be used on HYUNDAI vehicles (research method, «Normal») or higher. Use of leaded gasoline will damage the catalytic converter (OG) and malfunction of emission control systems. This can also lead to increased maintenance costs for your vehicle. To avoid the possibility of refueling the vehicle with leaded fuel, the vehicle's filler neck is designed to accept only a reduced-diameter refueling nozzle used to supply unleaded fuel.
Note:
- In some countries, Hyundai vehicles are supplied that have the ability to run on leaded fuel. If you intend to use leaded fuel, please consult your authorized HYUNDAI dealer about the possibility of using leaded fuel in your vehicle.
- The octane number of unleaded and leaded gasoline is identical.
Use of diesel fuel
On Hyundai vehicles, diesel fuel with a cetane number of 52-54 must be used. Due to paraffin crystallization, the viscosity of diesel fuel increases significantly with decreasing temperature. Therefore, two types of diesel fuel are used: "summer" And "winter".
- At temperatures above -5°C, use "summer" diesel fuel.
- At temperatures below -5°C, use "winter" diesel fuel.
Monitor the level of fuel in the tank: If the car stalled due to the cessation of the sun-supply and, then in order to be able to start the engine again, it is necessary to remove air from the fuel supply system.
Attention:
- Do not allow gasoline or water to enter the fuel tank. If this happens, it is necessary to drain the gasoline or water from the tank and bleed the fuel supply system to avoid clogging the injection pump and damaging the engine.
- In winter, in order to avoid the troubles associated with the crystallization of paraffin, when the air temperature drops below -10°C3, kerosene can be added to diesel fuel. The maximum concentration of kerosene in diesel fuel must not exceed 20%.
Is it possible to use gas oil?
gas oil (mixture of 90% unleaded gasoline and 10% ethanol or ethyl alcohol) can be used on. your Hyundai car. However, if this results in a reduction in engine performance, the use of 100% unleaded gasoline is recommended.
Do not use fuel with an inappropriate amount of alcohol or alcohols other than ethanol.
Don't use methanol
It is not allowed to use fuel containing methanol on your Hyundai vehicle (wood alcohol). These types of fuels can reduce engine performance and damage fuel system components.
Attention: The Hyundai New Vehicle Warranty does not cover damage to the fuel system and reduction in engine performance caused by the use of methanol or fuel containing methanol.
Environmentally friendly fuels
In low air pollution circuits, HYUNDAI recommends the use of fuels containing cleaning additives to help prevent engine deposits. Such fuel will contribute to cleaner engine operation and better performance of emission control systems.
Trips abroad
If you are going to drive your Hyundai vehicle to another country:
- Follow all rules regarding registration and insurance.
- Find out about the availability of the fuel used.
